Computing Lyapunov Exponents using Weighted Birkhoff Averages
E. Sander, J. D. Meiss
The Lyapunov exponents of a dynamical system measure the average rate of exponential stretching along an orbit. Positive exponents are often taken as a defining characteristic of c…

Proportions of Incommensurate, Resonant, and Chaotic Orbits for Torus Maps
E. Sander, J. D. Meiss
This paper focuses on distinguishing classes of dynamical behavior for one- and two-dimensional torus maps, in particular between orbits that are incommensurate, resonant, periodic…

Resonance and Weak Chaos in Quasiperiodically-Forced Circle Maps
E. Sander, J. D. Meiss
In this paper, we focus on a numerical technique, the weighted Birkhoff average (WBA) to distinguish between four categories of dynamics for quasiperiodically-forced circle maps. R…
